To all whom it may concern.-

Be it known that I, EDWARD CRAIG, a oiti-- zen of the United States of America, and resident of St. Joseph, Berrien county, Michigan, have invented a certain new and useful Improvement in Machines for Making Butter-Dishes, of which the following is a specification.

My invention contemplates an improved and highly efficient machine for automati-' cally converting wood veneer or paper or other suitable sheet material into butter dishes or trays of any desired or well known pattern.

Generally stated, the object of my inven-' tion is the provision of a simple, compact, and highly efiicient and practical machine for making butter dishes or trays of any.

suitable, known, or approved form or pattern. Y

A special object of my invention is the provision of an improved construction and arrangement whereby a machine of this character may be run at high speed without danger of breakage, and with practical certainty of the production of perfect trays, and with comparatively little noise and vibration.

Another object is the provision of a simplified and improved arrangement for feeding the wood veneer or paper.

A further object is the provision of a novel and improved cam and eccentric arrangement for operating both the feeding and forming and stapling devices.

Another object is the rovision of an improved construction and arrangement of the dies and the means for forming the materia into dish or tray form.

A further object is the provision of an improved construction and arrangement of the knives and cutting mechanism for shaping the blanks from which the dishes or trays are made. I

It is also an object to provide certain details and features of improvement tending to increase the general efiiciency and serviceability of an automatic butter dish machine of this particular character.

To the foregoing and other useful ends my invention consists in matters herein set forth and claimed.

In the accompanying drawings -Figu r is a side elevation of an automatic butter dish machine involving the principles of my invention. Fig. .2 is a front elevation of the machine shown in Fig. 1. Fig. 3 is a rear elevation of the machine shown in Fig. 1. .Fig. 4 is a vertical section online 44, in Fig. 2. Fig. 5 is a'vertical section on line 5.5 in Fig. 4. Fig. 6 is a front elevation of the upper portion of the machine, showing the mold or-hollowv die and adjacent parts, in vertical section. Figs. 7 and 8 are detail views of the lever connections for operating the stapling mechanism." Fig. 9 is a bottom plan of the knives andthe block upon which the latter are mounted. Fig; 10 is a vertical section on'line 10-10 in Fig. 9. Figs. '11 and 12 are detailed perspective views of the knives involved in the cutting arrangement illustrated by Figs. 9 and 10.. Fig. 13 is a perspective view showing the anvil or table upon which the blanks. are cut. Fig. 14 is a perspective of one of the blanks from which the butter dishes are made. Fig. 15 is a perspective of a completedbutter dish. Fig. 16 isa sectional view of the clench-blocks which are mounted on the plunger or form. Fig. 17 is a vertical sectional view .o fo-ne of the stapling mechanisms, showing the adjacent portion of the form'in elevation. Fig-18 is a section on line .18-18 in Fig. 17. Fig. 19 is a plan of one of the clenoh-block devices which are secured to the opposite sides of the form or plunger.

, As thus illustrated, my invention comprises a frame or body A, adapted to provide bearings for the different shafts and movable parts of the machine, and adapted to support certain of the operative parts in suitably elevated positions. A driven shaft 3 is mounted in. suitable bearingsin the frame or body, and is gear-connected, through the'medium of a pinion b and a ear I), with the driving-shaft C. A pulley and other suitable arrangements can be employed for driving the shaft B." The shaft C is mounted in bearings a in the frame or body and, as 'a means for reciprocating the knives, is provided at eachend with eccentrically arranged pins or reduced end portions 0. These'eccentric portions 0 are of less diameter than the body of the shaft, although integral therewith, and are adapted to rotate in blocks a, which latter are in turn adapted to reciprocate horizontally in the lower ends of the vertically reciprocating side members ,E of the frame whereon the. knives are mounted. These members E are mounted to slide in ways formed by bolting the pieces a to the sides of the frame or body, and are provided at their lower ends with openings a. providing ways for the horizontal reciprocation of the blocks 0. Thus, through the medium of the eccentric ortions c and the blocks 0 the rotation of t e shaft C is converted mto an even and smooth up-and-down motion or reciprocation on the part of the members E of the frame which carries. the kIllVGS'fOI cutting. the blanks. The said means for cutting the blanks comprises a hor zontal cross-piece 6 adapted to rigidly connect the upper end portions of the side members E, and adapted to serve as the means for supporting and giving a vertical reciprocation to the block or carrier e to which the knives are directly attached.

With respect to the form of blank shown in Fig. 14, and the consequent necessity. of rounding thecornersof theblank and making the cuts 1 and the scoring 2, the said knives are arranged as shown in F g. 9.

The knife e is curved at each end, so as to cut' off a suitable portion of the veneer X,

which, it will be seen, is 'fed to the forming .and stapling mechanism: over the smooth upper surface of the machine-that is to say, over the horizontal table portion a of the frame or body. The other corners of the blank are at the same time rounded by the action of the short curved knives a, while the cuts -1 are made by the short straight knives e. The scorin 2 is done by the obliquely arranged knives e, and by transversely arranged knives e. i It will be understood that the edges of the difierent knivesare so relatively adjusted that 6 e? and e pass entirely through the wood veneer or paper or other suitable material, while e and 6 materia a a As illustrated, a very satisfactory and efficient arrangement is employed for holding these knives in place. The carrier or block e to which the knives are directly secured,

islpreferably provided 3 with knife-seats e, and it is against these seats that the knives are tightlyclamped by the actionof the clamping o supporting the knives b means of removableblocks e and e 9, an by'prov'idin bent orangularly shaped jaws e having is readed :openings'adapted to engage the threaded ends ofthe bolts e 'It-will be'seen that a rotation of these lbolts will cause the jaws e to 'drawthe different knives tightly against the opposing or inner faces of the knife-seats e". The knives 'e can be given a-delicate and accurate adjustment by means of the adjusting screws e Thus the knives are embodied in a unitaryand self-contained structure or element of the, machine, and this unitary or self-contained knife structure can the lpass only partlythrough the said ltse This is accomplished by be removably'secured to the cross-piece e by means of bolts or screws 6 It is, of course, desirable to provide a simple and eflicient anvil or device for supporting the veneer or other material while it is being cut-that is to say, an arrangement .which will sustain the pressure of the knives. Fig. 13 illustrates a sim 1e and effective arrangement for accomphshing this purpose. It consists, as illustrated, of a block 'F provided with Babbitt metal adapted to receive the sharp edges of the knives. This Babbitt metal can be run into the block in the manner shown in Fig. 13, so as to provide a narrow stri ofmetal having the out line of the edges 0 the knives. It is obvious,

however, that this Babbitt metal can bedis posed in an suitable or desired manner. The block 4 is slipped into a seat in the frame or body provided by the cross-piece f, which extends across the machine and is bolted at its ends to the side portions of the frame. As a means for preventing the knives from objectionably ullin or lifting the blanks away from the lock the machine is preferably provided .at each side with plates f adapted to reach over and clamp upon the block F, and adapted to provide supports for the guards f. These guards are, it will be seen, bent up at their rear ends, so as to permit the veneer or other material to slide readily beneath them, and are also provided with openings f through which the knives may pass and operate on the material from which the dishes or trays areconstructed. Thus it will be seen that the cutting mechanism is ofa very simple and efiicient form or construction. Both the knives and the anvil or cutting block are readily removable, either for the purpose of repalr or substitution, and are susceptible of nice adjustment.

The improved and highly efficient arrangement for feeding the veneer or other suitable material over the table a comrises a lever G which is pivoted at its ower end to the frame or body, and which is connected at its upper end with the dog 9 or device for enga I ing and shoving the material forward. he said connection between the said lever and dog preferably consists of a link 9. As illustrated, the dog 9 has a foot 9 of a roughened character and adapted to engage and thrust the material 1 ter bearing .down on the top of the sliding I bar. A plate 9, together with apieceof material g, suitable for pressing in the roove g of said bar, constitute the means or*removably clam ing timber in place in the arm 9*, and, with the adjusting screws 9", permit the takin up of wear between the vertical back sur ace of this bar and the opposing vertical surface of the arm In this way, the bar 9, which is dove-tailed in cross-section, is zadaptedto slide back and forth and toward and away from the knives and cutting devices. As stated, the dog 9 is pivotally mounted upon the end of this bar 9, and is adapted to reciprocate in unison with the latter. Consequently, a forward stroke of the lever G will cause the dog 9 to press hard upon the veneer or other material, and will, at the same time,

cause the dog and the bar 9 to slide forward a movable portion h, which normallyhan-gs carrying the sheet of veneer or other material with them. The gripping, it will be seen, of the dog on the material is of a positive and certain character, and the ar-- rangement in this way is calculated to reduce uniformity and certainty in the coding action. A backstroke of the lever G then positively lifts the foot of the dog from oil the veneer, and at the same time draws the dog and the bar 9 back into a position to again grip the veneer. In this way, the feeding mechanism is adapted to produce an intermittent feeding movement of the veneer beneath the knives.

-The means for operating the feeding mechanism comprises an eccentric cam 92 mounted on the drive-shaft C, and provi with an'eccentric strap 9 having a suitable g with-an interme preferably of an upper die'or hollow mold H, mounted immediately beyond the cutting mechanism, and a'lower'die or solid plunger 1. The moldI-I can be secured to the cross member h of the body or frame, and "has a concave undersideladapted to re--' ceivesaid plunger. The two'si e portions of the mold are spaced 'apart'ito provide slots for the staplers to work through. As a matter of special improvement,the said die or hollow forming-member is provided with a distance below 'the hinder stlrfa'ce' of the moldpand which is adapted-'to engage the portions-3 of the .blan'k before the 'stationary or body portion *of the'molden ages the remaintng portions of the blank. t' willbe seen that the said mold' is constructed with two rigidly connected side portions between which the said movable section it :is adept to move up and down. Thus, in the operation, these portions 3 are first bent down, so as to allow the hollow mold to fold the portions 4 on top, as shown in the completed article. This movable section it of the mold is supported by rods b adapted for vertical reciprocation and held normally down by a spring h The said rods serve also to prevent the section 72. from turning about a vertical axis. This spring is secured at its lower end to a stationary portion of the frame, and at its upper end to the crosspiece it" which connects the said rods. V

The cross-piece h canibe provided with a projection k adapted to rest normally, or nearly so, upon the rubber cushion or buffer it. Thus in the operation, the plunger in rising carries the blank upward w1thit,

thereby forcing the mold section It upward, so as to lap the portions 4 upon the portions 3 of the blank. When the plunger starts down, the spring it returns the mold-section h to its normal or depressed position, and the" rubber cushion or buffer it at this time acts as anoi'seless stop to limit its downward motion. The said plunger I is removably secured to the upper end "of the plun er rod or bar '2', which latter is mounted or vertical reciprocation in a box-like bearing c". The lower end of said plunger rod is connected by a link z' with the eccentric strap '2' carried by an eccentric cam 2 onthe shaft C. This strap i is adapted to act as a levenit having a shiftin fulcrum by reason of its connection with t e lower portion of the frame or body throu h the medium of a swinging link i. t is thus adapted, as stated, to act as a lever, the power being applied between its ends, and its vertical vibrato moyement, caused by the rotation of the s aft O and cam i, causing the vertical reciprocation of the plun er I. During the operation of the machine t is form is constantly moving up and down. Now the veneer, during the operation of the machine, is given an intermittent feeding movement beneath the knives, which movement of the veneer serves to not only bring a fresh portion of the veneer beneath the knives, but serves also to push the previously cut blankjfrom beneath the knives and into a position to be caught between the mold H and the form I.- The form and mold comin together reduce the blank to the desire form or contour, and at this point, the staples 5 are then driven through the end portions :of the tray or dish for the purpose of fastening the lapped portions 3 and 4 :together. i i

The stapling mechanism for driving the said staples can be of any suitable known unapproved character. For example, two stapling mechanisms J may be employed, as shown. more -'clearly in Fig. "6, these two mechanisms being arranged at. opposite sides of the machine, and tilted outward at their upper ends, so as to permit the staples to be driven at right angles to the sloping or beveled end-surfaces of the plunger. As illustrated, each stapling mechanism comprises a staple former j closely and slidingly associated with a staple driver j. The driver, it will be seen, is rigidly secured to the head i which latter is carried by the upper end of the rod j This rod 9'3 is mounted for vertical, or substantially vertical, reciprocation in a bearing 1'', which is rigidly secured to the frame or body of the machine. On the other hand, the staple former j, which is provided with two prongs j, is yieldingly connected with the head 7' through the medium of a spring j. The driver 7" has an end or driving portion adapted to slide between the said prongs j of the staple former. The anvil or loop-bar j is removably secured to the lower end of a lever j, which latter is pivoted to the stationary or body portion 9' of the stapling mechanism. This anvil or loop-bar 1s, it will be seen, provided with a notch or opening 3' adapted to receive the wire Y, as it is fed through and across the lower end of the mechanism, and furthermore this anvil or loop-bar is removably secured tothe lever i by means of the screw or bolt 1'. It will be seen that a slight shoulder X at the lower end of the lever prevents the loop bar from turning on the screw. A pin 7' on the upper end of the said lever, and the cam finger j carried by the reciprocating head 9', constitute the means for causing the loopbar 9' to be alternately thrust into the path of the staple former and driver and removed therefrom; The overhanging portion j is adapted, it will be seen, to prevent the long middle ortion of the staple from bowing or bending upward when it is formed, it being observed, at this juncture that. the staples which are used for fastening the ends of the dish are'necessarily quite broad.

The simultaneous movement of the staple former and driver is obtained by providing the two with openings which, when they register, areada-pted to contain the cylindric portion 7' of a short reciprocating pin or shuttle-like member. This short locking pin is adapted to be, reciprocated through the staple driver and former by the stationary cams or beveled surfaces j and j". Thus, when the head reciprocates, it first causes the staple driver and former to move in unison, the short. pin or locking member then encountering the cam or bevel 3', so as to reciprocate said locking member to an extent to bring its narrow portion 7' into the position to slide downward through the slot j". The driver and former then become unlocked, allowing the driver to complete the balance of the stroke alone.

In other words, the initial movement of both staple driver and former causes the staple former to bend to cut oil a short length of wire and bend it over the loopbar, and when the staple is thus ready to be driven, the staple driver and former'are then unlocked from each other, and the staple driver continuing its movement drives the staple into the material of the dish or tray. Preferably, the wire is fed through a small adjustable tube 7', and the lower end of the prong j at this side of the mechanism is adapted to act as a knife to shear or cut off a length of wire. The set-- screws are employed for regulating the pressure of the plate which latter bears against the outer s1des of the staple former and driver. During the driving of the staple, the lower ends of the prongs j rest upon the dish or tray, the spring j permitting the staple former to thus remain stationary during the time the staple ,driver is being moved downward for the purpose of inserting the staple.

Any suitable means can be mounted on the plunger or form I, for the purpose of clenching the ends of the staples. For example, the clench-block arrangement can be of. the character shown in Figs. 16 and 19, which are on a much larger scale than Figs.

17 and 18. An arrangementof this character, when employed, is mounted at each end of the form or plunger. Each clenching device consists of a, clench-block made in three sections, a long middle section K and two narrow but higher end scctionsk. Pivoted levers k are employed as the means for supporting the clench-block thus made in sections in place back of the plate is, which latter is secured to the inclined end of the form, as shown in Figs. 17 and 19. The

spring is is vemployed for holding the clench-block sections in their normal positions. -When a staple is driven, its points or:' ends first strike the cavities is in the upper ends of the clench-block sections it, and

the downward pressure on these sections.

then cause the levers 7a to tilt and raise the long middle section K. Thus the points are partiallyturned, and the middle section K of the clench-block then rises to complete the clenching on the under or concave side of the dish ortray. This is shown quite clearly in Fig. 15. A clench-block arrange ment of this character is very efficient and satisfactory in use. It insures a properand with comparatively. little noise.

thcrmore, it is capable of thus rapidly turn- L, through the medium of the vibratory lever Z. This in turn produces the desired reciprocation of the heads 9?, these heads '7' being adapted to either reciprocate upon the rod 7' or to move with the said rods, thelatter sliding in bearings j. These, Or other similar arrangements can be employed for securing an even and satisfactory reciprocation of the heads which carry the staple drivers and formers.

It will be observed that the two eccentric arrangements, and also the cam l ,are all so relatively mounted upon the shaft 0 that thedifierent stepsin the operation of making a butter dish occur in their proper sequence. In other words, the forming and stapling devices are forming and stapling a butter dish at the Same time that the knives are cutting the next blank. E

The feeding of the veneer is, it willbe seen, accomplished when the-knives are up, and the completed blank is pushed between the mold and formjust-prior. to-the time at: which thesetWo forming instrumen'talities are brought together. g 2

Any. suitable arrangement can be eniployed for feeding the wire Y. For example, the eccentric strap 'g can be provided at its other side withan arm M, and,

this arm can be pivotally connected-with the lower end of the rod m. To the upper end of the latter is secured a suitable'pawl or% dog m. This pawl or dog is adapted to engage the ratchet-wheel'm so as to cause the feeding rolls m and m to gii' e the wire. an intermittent forward feeding movement. When the rod on goes down, the feeding mechanism remains inert, but when the, cam g revolves to a point to cause this red m to rise, the feeding rolls are then rotated-"t0 an extent to give the wire the proper-or desired extent of feed. The spring m connecting the rod m to the arm M, can be em plovedas the means for keeping the pawl or-dog m pressed firmly against the ratchet wheel m". In this way, the eccentric arrangement which operates the veneer fed is also employed for operating the wire feed. The wire can be held by a reel Z or any other suitable similar' device.

The machine thus constructed is simple,- compact, and of a very practical and serviceable nature. It is capable of very high speed, and of a consequent rapid production of the trays or dishes, without injurious vibragon,

is adapted to act as an ejector when the plunger orform I descends. In other words, its spring will cause it to eject the finished tray vor dish from the hollow mold. The spring- N which connects thelever l with the stationary bearing box 5 is adapted to maintain the stapling devices in normal positions.

which the trays or dishes areto be made,

Any suitable or approved means can be employed for receiving thefinished product from the mold when the plunger goes down. The scoring knives can, of course, if such is desired, be formed integral-that is to say, the knives 6 can be formed integralwiththe knives e, thus making only two scoring lmives. It; is, obvious, however, that this construction and arrangement of knives can be=var1ed or modified in any suitable or desired -manner. Furthermore, the staple clenching arrangement shown I in Figs. 16 and 17 can-be changed or modified more .or less, the essential feature consisting of a yielding outside clenching device anda movable center. As illustrated, the outside clenching device .con'sists'of the two sections: "k, is, but it isobvious that these two sections can be rigidly connected, so as tomove as one'member. Other arrangements and constructions are obvious. u I

In Fig. 4 it will be'seen that a links" is mounted .upon a pivot or axis 5 carried-on-a block or bracket 71' secured tothe base of-the machine. This block 2? is supported u-pon'a wedge block i which latter is operated by an adjusting screw 5, and the parts: are held in place on the base by screws 21 whereby the axis i can be raised and lowered. This, it will be seen, will serve to regulatethe operation of the vertically reciprocating plungeror form. The lever Z is also pivoted .or fulcrumed upon the pin or axis '5", so. that this lever andthe said link have a common axis.
